Abstract of the Disclosure Images are formed on plain paper using imaging sheets having a coating containing a chromogenic material and a photosensitive composition with at least the photo- sensitive composition encapsulated in a layer of rupturable microcapsules as an internal phase by a process which comprises image-wise exposing the imaging sheet to actinic radiation placing the imaging sheet in contact with a sheet of plain paper with the layer of microcapsules adja- cent the sheet of plain paper, subjecting the microcap- sules to a uniform rupturing force, the steps of subjecting the layer of microcapsules to the rupturing force and placing the imaging sheet in contact with the sheet of plain paper being conducted such that the chromogenic material is image-wise transferred to the sheet of plain paper, and applying a developer material to the surface of the sheet of plain paper to which the chromogenic material is transferred, the developer material thereupon reacting with the chromogenic material and producing a visible image.
